Be it known that I, JOHN MULLALY, of New York, in the county of New Yorkand State of New York, have invented a new and useful Machine forMelting Snow and Ice in the Streets; and I do hereby declare thefollowing to be a full, clear, and accurate description thereof,reference being had to the accompanying drawing and letters and figuresmarked thereon, in which the figure shown is a side view and partialsection of my invention.

My invention has for its object to provide means for the speedy removalof snow and ice from the streets of cities; and it consists of a machineadapted to discharge heated air with steam, natural or superheated, uponthe snow or ice, melting the same and causing it to flow off in the formof Water.

Referring to the accompanyingdrawin g, A shows a frame mounted on wheelsB B, which may be flanged, if desired, to adapt them to railroad tracks,or runners may at times be conveniently substituted for wheels. 0 is afurnace mounted on the frame A, surmounted bythe steam-boiler D andhot-air chamber D.

Beneath the frame is a tank, E, communicac ing with the boiler D bypipes d, and with the hot-air chamber D by pipes d (1 representsexpanded portions or fan-boxes on the pipes d, within which are fans 6mounted on the shaft 6, to which motion is communicated by a gear, orsimilar connection, from the driving-wheels B. The pipes 61, instead ofrunning directly, as shown, from the boiler to the tank, may passthrough the furnace, whereby the steam may be superheated.
